n OpenVMS usage:longword_signed type: longword integer (signed) access: read only mechanism: by reference Number of elements in vector x. The n argument is the address of a signed longword integer containing the number of elements. If you specify a value for n that is less than or equal to 0, then the value of dotpr is 0.0. x OpenVMS usage:floating_point or complex_number type: F_floating, D_floating, G_floating real or F_floating, D_floating, G_floating complex access: read only mechanism: by reference, array reference Array containing the elements to be accessed. All elements of array x are accessed only if the increment argument of x, called incx, is 1. The x argument is the address of a floating-point or floating-point complex number that is this array. This argument is an array of length at least: 1+(n-1)*|incx| where: n = number of vector elements specified in n incx= increment argument for the array x specified in incx Specify the data type as follows: Routine Data Type for x BLAS1$VSDOT F-floating real BLAS1$VDDOT D-floating real BLAS1$VGDOT G-floating real BLAS1$VCDOTU and F-floating complex BLAS1$VCDOTC BLAS1$VZDOTU and D-floating complex BLAS1$VZDOTC BLAS1$VWDOTU and G-floating complex BLAS1$VWDOTC incx OpenVMS usage:longword_signed type: longword integer (signed) access: read only mechanism: by reference Increment argument for the array x. The incx argument is the address of a signed longword integer containing the increment argument. If incx is greater than 0, then x is referenced forward in array x; that is, x[i] is referenced in: x(1+(i-1)*incx) where: x = array specified in x i = element of the vector x incx= increment argument for the array x specified in incx If incx is less than 0, then x is referenced backward in array x; that is, x[i] is referenced in: x(1+(n-i)*|incx|) where: x = array specified in x n = number of vector elements specified in n i = element of the vector x incx= increment argument for the array x specified in incx y OpenVMS usage:floating_point or complex_number type: F_floating, D_floating, G_floating real or F_floating, D_floating, G_floating complex access: read only mechanism: by reference, array reference Array containing the elements to be accessed. All elements of array y are accessed only if the increment argument of y, called incy, is 1. The y argument is the address of a floating-point or floating-point complex number that is this array. This argument is an array of length at least: 1+(n-1)*|incy| where: n = number of vector elements specified in n incy= increment argument for the array y specified in incy Specify the data type as follows: Routine Data Type for y BLAS1$VSDOT F-floating real BLAS1$VDDOT D-floating real BLAS1$VGDOT G-floating real BLAS1$VCDOTU and F-floating complex BLAS1$VCDOTC BLAS1$VZDOTU and D-floating complex BLAS1$VZDOTC BLAS1$VWDOTU and G-floating complex BLAS1$VWDOTC incy OpenVMS usage:longword_signed type: longword integer (signed) access: read only mechanism: by reference Increment argument for the array y. The incy argument is the address of a signed longword integer containing the increment argument. If incy is greater than or equal to 0, then y is referenced forward in array y; that is, y[i] is referenced in: y(1+(i-1)*incy) where: y = array specified in y i = element of the vector y incy= increment argument for the array y specified in incy If incy is less than 0, then y is referenced backward in array y; that is, y[i] is referenced in: y(1+(n-i)*|incy|) where: y = array specified in y n = number of vector elements specified in n i = element of the vector y incy= increment argument for the array y specified in incy
